Abstract
A single support device (30) is adapted to support and secure a machine (34) at least one sheave (38) and a plurality of termination members (44, 46). The single support device (30) is conveniently installed within a hoistway (26) or within a machine room (90). The machine (34) and sheave (38) may be premounted to the support device (30) and the entire assembly can be lowered into position by crane (300).
Claims8
A support device for a machine-roomless elevator system, comprising:
- a machine supporting portion that secures a machine comprising a motor in a selected position in a hoistway;
- a termination supporting portion that secures a plurality of termination members in a selected position, the termination members being configured to secure an end of associated load bearing members near the selected position;
- and
- a sheave supporting portion that supports at least one sheave, the supporting portions being secured together to form a single structure that supports the machine, the termination members and the sheave, the single structure being located inside the hoistway, the supporting portions each comprise a plurality of metal sheets secured together.
